`SHUTTER-FASTENER.

SPECIFICATION forming part of Letters Patent No. 459,767', dated September 22, 1891.

Application filed January 26, 1891.

To a/ZZ whom, t may concern:

Beit known that I, WALsTErN E. ROBIN- SON, of Bellport, Suffolk county, and State of New York, have invented a certain new and useful Improvement in Fasteners for Shutters or Blinds, of which the following is a specification.

My improvement relates to fasteners for shutters or blinds such as are used outside of ro houses. The fasteners employed with such shutters or blinds are commonly constructed to secure shutters or blinds when closed and also when opened against the wall of a house. A common form of fastenercomprises alever I5 which is provided with a hook projecting from that side of the shutter or blind which is outermost when the shutter or blind is closed, and provided at the inner end with another hook at the opposite side of the blind zo or shutter and adapted to engage with acatch on the sill of a Window. One of these hooks secures the shutter or blind when open and the other when closed. By manipulating that end of the lever which projects from the side of the shutter or blind that is innermost when the shutter or blind is closed the hook at the other end of the lever may be made to engage or disengage with a catch on the wall of a building. This hook, which is intended to 3o fasten the shutter or blind when open to the wall of a building, being connected with the other hook of the fastener, constitutes a means whereby the fastener maybe manipulated to unfasten the-shutter or blind when it is closed. It is desirable to have the outside hook en gage with a vertically-arranged catch or piece, because a catch or piece so arranged will not interfere with the action of this hook by reason of the sagging of the shutter. The out- 4o side hook of a fastener, therefore, preferably ext-ends laterally rather than vertically.

The object of my improvement is to produce a fastener of the kind referred to having a laterally-extendin g hook, but constructed so as to be incapable of effecting the disengagement of the inner hook from the catch on the window-sill with which it engages.

The improvement consists in the combination of a shell or frame constructed for attach- Serial No. 379,027. (No model.)

ment to a shutter or blind anda lever pivoted 5o within the shell or frame and having at one end a lateral hook, which is intended. to project from the outside of the shutter or blind and engage'with the vertical edge of a catch Aon the wall of a building, and at the inner end having a portion provided with a vertical hook and hinged to the main portion of the lever independent of its pivot, so that it can rise and fall to engage with the horizontal edge of a catch on a window-sill.

In the accompanying drawings, Figurel is a vertical sect-ion of a shutter or blind, awindow-sill, and a fastener embodying my improvement. Fig. 2 is a horizontal section of the same. Fig. 3 is a. horizontal section of 65 the shutter or blind in a different position of a wall of a building and of a catch embodying my improvement.

Similar letters of reference designate corresponding parts in all the figures.

A designates a frame (here shown as made in the form of a cylindric shell) having external screw-threads a. It is intended to be inserted in a hole formed horizontally in a shu tter or blind S, and the screw-threads are designed to retain it in place. At one end it has a flange a', and this end is intended to project from that side of the shutter or blind which is innermost when the shutter or blind is closed. This end, therefore, may be re- 8o garded as the inner end of the shell. The shell may advantageously be made in two semi-cylindric sections fitted together, with their meeting edges in a horizontal plane.

The inner end of the shell is shown as provided with a rectangular mouth d'2 and the outer end with a rectangular slot CL3.

B designates a lever, which isA fitted within the shell A and fulcrumed therein by means of a vertical pivot-pin b. This lever extends 9o through the outer end of the shell, and at the outer end, or, in other words, at the end that extends through the outer end of the shell, it is provided with a laterally-extending hook b. This end works through the slot aof the o5 shell A. The inner end of the lever B has a hinged section B', that extends through the mouth a?, with which the inner end of said shell is provided. This section isindependent of the pivot-pin of the main part and is oonneeted to the main part of the lever by a horizontal pivot-pin [12, and Consequently is free to` rise and fall. It has a hooked end b3. As here shown, the hook ot this end is a double hook extending both upwardly and downwardly below the body of the section B. Only one portion of the hook will be used at a time, and the ad vantage of making a double hook is that it enables the fastener to be used in different positions for a left or a right shut.- ter or blind. A spring C is combined with the shell A and lever B. It normally holds the said lever in one position andreturns the lever to this position after it has been moved out of it.

The lateral hook b on the outerend of the.

lever B engages with a eateh D, fastened to the wall of a house and having its edge in a vertical plane, As the shutter or blind S swings open the rounded edge of the hook b will come in Contact with the edge of the eateh D and will travel along the same, the lever B being osoillated to permit this. As soon as the shoulder or nose of the hook Comes opposite the edge of the catch the hook will swing into its normal position and engage with the catch. The hook will remain in engagement with the eateh until the lever B is oseillated by pulling the hinged section B. NVhen the shutter or blind is closed, the nose of the hook lf3 will slide up over the top of a Catch E, extending from the Window-sill and having its top edge in a horizontal plane, and after passing over the same the hook will drop down and engage therewith. This catch E Will be so wide that the shifting of the lever horizontally bya force applied to its outer end will not disengage the hook Z13 from said catch E.

It will be seen that in my fastener there are hooks which are movable in different planes.

That I Claim as my invention, and desire to secure by Letters Patent, is-

The combination of a shell or frame constructed for attachment to a shutter or blind and a lever consisting' of a main portion pivoted on a vertically-extending pin within the shell or frame and having a lateral hook at its outer end and a portion provided with a vertical hook and hinged to the main portion independently of the pivot-pin of said main portion, substantially as specified.

ln testimony whereof I have signed my naine to this specification in the presence of two subscribing witnesses.
